Unix. Possibly, the longest living entity in the computer land where nothing
survives more than a couple of years, a decade at the most. It has been around
for more than two decades, owing its lingevity to the ruggedness built into it
and its commands.
This book has two parts. The first part is a journey into the vast expanse that
is Unix. The intent is to make you aware of the underlying philosophy used in
development of myriads of Unix commands rather than telling you all the
variations available with them. The second part takes you into the murky depths
of Shell Programming and System Administration. You would find a detailed
coverage of several aspects of Bourne Shell Programming.
